Buffersīuffers are arrays of 32 bit floating point values with a small descriptive header. Buses are indexed by integers beginning with zero. Synths can send control signals to each other via a single global array of control buses. The number of bus channels defined as inputs and outputs do not have to match that of the hardware. Immediately following the output buses are the input buses, read from the audio hardware inputs. The lowest numbered buses get written to the audio hardware outputs. Using buses rather than connecting synths to each other directly allows synths to connect themselves to the community of other synths without having to know anything about them specifically. Audio buses are indexed by integers beginning with zero. Synths send audio signals to each other via a single global array of audio buses. Synth Definitions are referred to by name. Synth Definition files are created by the SuperCollider language application and are loaded into the synth server. Synths are created from Synth Definitions. Synths can have their own local controls that are set via commands to the server. They read input and write output to global audio and control buses. They can be addressed and controlled by commands to the synthesis engine. SynthĪ Synth is a collection of unit generators that run together. See RootNode and Default Group for more info. If the server was booted from within SCLang (as opposed to from the command line) there will also be a 'default group' with an ID of 1 which is the default target for all new Nodes. At startup there is a top level group with an ID of zero that defines the root of the tree. The Nodes in a Group may be both Synths and other Groups. The Nodes within a Group may be controlled together.
A new Node may be added to the head or tail of the group. GroupĪ Group is a collection of Nodes represented as a linked list. The tree defines the order of execution of all Synths. Main Design Concepts NodeĪ Node is an addressable node in a tree of nodes run by the synth engine.
#SERVER ARCHITECT DEFINITION GENERATOR#
The Unit generator API is a simple C interface. Unit generator definitions are Mach-O bundles (not to be confused with CFBundles). Synth definitions are stored in files generated by the SuperCollider language application. If MIDI is desired, it is up to the client to receive it and convert it to appropriate OSC commands for the synth engine. It is expected that the client will send all control commands. The synth server does not send or receive MIDI. The synth server and its client(s) may be on the same machine or across a network. Patching between modules is done through global audio and control buses.Īll commands are received via TCP or UDP using a simplified version of Open Sound Control (OSC).
All running modules are ordered in a tree of nodes that define an order of execution. Effects processes can be created and patched into a signal flow dynamically at scheduled times. While synthesis is running, new modules can be created, destroyed and repatched, sample buffers can be created and reallocated. The SuperCollider 3 Synth Server is a simple but powerful synthesis engine. NOTE: Converted to new help system 2010 by Jonatan Liljedahl.
